Q1 2026 Rustls Performance Update
Overview Offering top tier performance is a primary goal for the Rustls project. As such, the project has developed benchmarks representing some of the most performance critical functions and monitors them closely. The Rustls project periodically publishes test results that compare Rustls performance to other popular TLS libraries, OpenSSL and BoringSSL. The previously published test results are from July of 2025. The Rustls project is planning to start publishing performance reports more frequently going forward.
